Answer:

c This is the direct variation

Step-by-step explanation:

The equation for direct variation is y= kx

Solving this for k

y/x =k

So y/x must be a constant

a. 9/3 =3

2/7 does not =3 so this is not a direct variation

b 1/2 = .5

-3/6 = -.5

This is not the same so this is not a direct variation

c. 27/9 =3

18/6 =3

9/3 =3

This is a direct variation with a constant of 3

d 5/-7 = -5/7

1/-3 = -1/3

This is not the same so this is not a direct variation

1. $x-5\ \textgreater \ 2$

add 5 to both sides

$x\ \textgreater \ 3$

2. $x+2\ \textless \ -5$

subtract 2 from both sides

$x\ \textless \ -7$

3. $x-2\ \textless \ 2$

add 2 to both sides

$x\ \textless \ 4$ and it's the 4th graph option

4. $x+5 \geq 10$

subtract 5 from both sides

$x \geq 5$ and it's the 2nd graph option

5. $x-5\ \textgreater \ -10$

add 5 to both sides

$x\ \textgreater \ -5$
